This probably isn't a common problem with an easy fix, but I thought I'd ask anyway.

The other day my dash illumination lights died. It wasn't the dash itself because everything except the lights that come on with the headlights died.

Also dying with it are the ignition key illuminator thing, the beeper which tells you the lights are on or you left the key in the ignition, and the turbo timer. Now when you switch the key to ACC it just goes off rather than into turbo timer mode.

It's not a fuse, because I checked them all. I can't read the Japanese on the fuse cover so I've no idea which one it is - hence checked all of them.

I found the wire that goes through the dash dimmer, and when the headlights are on it goes up to 0.3V instead of 12V, so I think it's just a wiring fault or possibly a loose or dead relay.

Does anyone know where the aforementioned items get their juice from? The problem would be somewhere behind that. Even if someone could tell me what colour wire it might be I could go hunting myself.

there is a good chance that the wiring from compliance where they fit the dimmer (behind the cluster) has come loose, seen it before - the old twist and tape method. Seems strange that the TT is playing up, sounds like it's lost a power source too. Park light circuit is normally red with a blue trace, good luck :D

Some more elaboration needed :D

I pulled the dimmer out and tested it, it's all ok. I also plugged the wires back in directly rather than running them through the dimmer, just to eliminate it as a possibility anyway. That bit of wire is after the other bits which don't work - ie, if it was the dimmer, then the beeper, ignition light, etc would all still work. Obviously the dimmer is not going to make it beep less etc. The bit which measures 0.3V is where the dimmer goes.

The turbo timer I'm guessing doesn't work because it needs a signal from the ignition switch that is somehow related to the now dead light and beeper. I'm pretty sure that once I fix this the turbo timer will start working normally again.

I decided to not pissfart around with it any longer and ask my mechanic if he knew of any good auto electricians familiar with Skylines. He said he did, and showed me his Cordia which had a brand new full custom wiring setup recently done by this guy. It looked better than factory, it had that black serpentine stuff covering all the wires in the engine bay and looked like showroom material. It took him a couple of days and only cost $400.

So I gave him a call to see if he could help, and he said it shouldn't be a problem. He does work onsite, and it's $20 call-out and $50 an hour. I don't imagine it'll take long for him to sort out, he's done a lot of Skylines in the past. He's booked out until next week but after he visits I'll update again and say how it went.

My mate said that one of his specialities is re-wiring GTS-t's to take RB26's :P

Possibly, but I've had a good look around there and wriggled lots of wiring to no effect. If the guy can come out and fix a simple loose wire that may do it again in the future, I think it'll be well worth the $70 (oh yeah, this guy guarantees his work and will come out and fix it again for free if it plays up).

Oh yeah, something else that happened yesterday, not sure if it's related. My passenger door central locking stopped working. I hope my whole wiring system isn't on its way out :P

It's all now working, thanks to the auto electrician guy that came around. There was a bodgy (non working) 12V feed into the ignition cluster which he found and isolated, but there was no way to trace it back to the source. So he rigged up a new set of wires from the fuse panel, and put a new inline fuse in that. Soldered up what needed to be soldered and put terminals in where needed, and it's now all good.

It can't really happen again because the wire is now very short and right at the fuse panel. About the only thing that can happen is the fuse will blow. But if anything in that area should happen again I should be able to figure it out myself.

Hippy does it work from the driver's door switch? Mine was working fine from that but nothing else, ie, not the alarm or the actual driver's door lock (which is meant to control all others for locking/unlocking). Really odd because I thought it was on the same circuit as the extra switch but apparently not.

While the guy was looking at it, it got into some weird-arsed half working mode where I could lock/unlock it once, but then it wouldn't respond for several minutes. I'm not sure if it was just time elapsed that let it work again or arming/unarming of the alarm or switching the ignition off/on. But now it's all good.

    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.  
    • For race cars, this is one part where I find having the roll cage bar having gone through a hole in the floor better than the build it up on a ledge inside... The Merc I help on, the main hoop ends are marked on the car, and the jack is marked... Jack goes under a few inches and lifts one whole side of the car up... Removes that fight for long slim jacks for race car duties!   My biggest issue for the daily drivers I work on, is my jacks don't go high enough. The jacks start out on a few blocks, jack it up, then start a second jack under it on more blocks, and then I can get an axle stand under it. My axle stands are presently in use, and are nearly fully extended. The car is sitting with barely more than a cm of clearance to get the wheel off the studs! Sarah's Kluger is the same, as it has an ungodly amount of droop available in the suspension and a distinct lack of good jacking points!
    • Happy? Yep, my to do list is getting shorter and shorter. Either this light approaching is the end of the tunnel, or I'm about to be hit by a train... Ha ha ha   Also, Duncan isn't that far out of town that you need to make a multi day drive out of it. 😛
